A new reading program may reduce the number of elementary school students who read below grade level. The company that developed this program supplied materials and teacher training for a large-scale test involving nearly 8500 children in several different school districts. Statistical analysis of the results showed that the percentage of students who did not meet the grade-level goal was reduced from 15.9% to 15.1%. The hypothesis that the new reading program produced no improvement was rejected with a P-value of 0.023.
a) Explain what the P-value means in this context.

Answer:

The solution to the given points can be defined as follows:

Step-by-step explanation:

In point a:

There is still a 2.3% chance which 15.1% of learners who also don't achieve a level by naturally-excluding specimens only will see if 15.9% is the population means value.

In point b:

Throughout the old system, 1352 learners must not read in classes, but 1284 should not write throughout academic performance throughout the new curriculum. A reduction, as well as the significance of such a decrease, would depend mostly on the cost of switching to the new initiative.

a. The explanation of the p-value should be explained below.

b. The suggestion that should not be considered is also explained below.

P-value and the suggestion not considered:

a. Since there is a still 2.3% chance that 15.1% of learners should not accomplish the level via naturally-excluding specimens only would watch in the case when 15.9% should represent the mean value of the population.

b. If we considered the old system, so 1352 learners should not read the class however, 1284 should not write the academic performance. So there is the reduction that based on the switching cost
